Gigabyte apparently has two custom Radeon R9 290 series cards with WindForce 3X 450W cooling system in the works, according to VideoCardz.

The new Radeon R9 290 and 290X graphic cards will be clocked at 1040 MHz, a 40 MHz gain for the 290X and a 93 MHz for the 290, both having a memory running at a 5 GHz value. They are also equipped with 4GB GDDR5 memory across a 512-bit interface, having the R9 290X featuring a Hawaii XT GPU with 2816 Stream Processors while the R9 290 features a Hawaii PRO with 2560 shaders. Unfortunately. there is no detailed information available at this point as to how the graphic cards were modified and all features/improvements included. But we do get to have a look at a quick preview of how they are going to look and the box they come in below.

It is also recommended by Gigabyte to have a 600 watts PSU for both cards, but this requirement probably won’t go through since the graphic cards are still equipped with only 6+8pin power connectors.
